Fluid mechanics 2
Also listed as: מכניקת הזורמים 2
Differential fluid mechanics done properly: Navier–Stokes derived rather than quoted, potential flow, boundary layers, and a first look at turbulence. The gateway to every fluids group in the school.

Compressible and high-speed flow, where fluid mechanics and thermodynamics finally meet. If you want anything to do with propulsion or aerospace, this is not optional in practice.

פרויקט מחקר למצטיינים 1
The honours research project, and the most direct on-ramp to a thesis in the catalogue. You pick a supervisor, produce results, and frequently continue the same problem into a masters.

פרויקט מחקר למצטיינים 2
The continuation of the honours project, where the results get deep enough to defend. Under the direct track this is already the first part of the masters thesis.

The second thermodynamics course, where cycles give way to real substances, mixtures and combustion. It is the anchor of the energy track and the reason most energy electives are open to you at all.

We also write the summaries.
This map tells you what a course contains. The summaries, the tutoring and the people who already took it are the part you get by joining.
The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
